Product Description

The KEYENCE FU-42 is a compact reflective fiber optic sensor head designed for precise detection of minuscule objects in confined spaces. It features a 0.5-meter fixed-length fiber unit with a 1.5 mm diameter, making it ideal for applications requiring minimal detection of objects as small as 0.01 mm. The sensor head has a minimum bend radius of 25 mm, ensuring durability and adaptability in tight environments. With an ambient temperature range of -40°C to +70°C, it operates effectively in various industrial settings. Weighing approximately 3 grams, the FU-42 offers reliable performance for precise detection tasks.
